Roof leak investigations in Walton on the Hill: local notes
Handmade clay tiles and tile-hung walls are typical of Surrey’s older houses. Horsham stone slab roofs survive on some old buildings in Surrey. Where water gets in depends a good deal on what the roof is made of and how it’s detailed. Historic houses like Fitznells Manor, about 5 miles north, show how far back building in the area around Walton on the Hill goes. If your house is among the older ones, expect a mix of original materials and later repairs on the roof, and any change of roofing material on a listed home needs checking with the council first.
For landlords with property near Tadworth station, finding the cause of a leak fast keeps a tenant’s home dry and the work focused. Homes near green spaces such as Betchworth Quarry and Lime Kilns can get more leaves in their gutters in autumn.

Roof leak investigations for homes and businesses in Walton on the Hill
A leak that comes and goes can be the hardest to pin down. Wind-driven rain, an overflowing gutter or snow melt may be what triggers it. Notes on when it leaks, and what the weather was doing, help us, along with any photos you’ve taken. We look for the clues it leaves behind, such as tide marks, stained timbers and damp underlay. Moisture detection shows which materials are still damp. We survey chimney stacks, lead flashings and valleys and parapet gutters, and people most frequently book us about damp underlay across a wide area and damp patches next to the stack.
In a village or hamlet like Walton on the Hill, older cottages and farmhouses often have roofs that have been patched over many years. A new leak may be fresh damage or the latest sign of long-term wear, and the difference matters, especially to an insurer. We look at what can be seen safely and set out what we find. Damp in old walls and timbers is slow to dry, so the sooner the cause is found the better.
Most points in the report come with a picture, so you can see each defect rather than just read about it. If something couldn’t be seen safely, the report is clear about it.

DIY checks: what’s safe
During heavy rain, look at the gutters from ground level or a window. Water spilling over the edge can point to a blockage or a sagging run.
Your own check is a good start, but it is not a survey. You will not see flashings, valleys or the backs of chimneys properly from ground level, and those are details a survey looks at closely.

How the survey works
A survey visit follows a simple order: we hear what you’ve seen, inspect the roof from every safe vantage point, photograph what we find and record our findings for the written report. It usually takes between one and two hours, more where the leak is intermittent or the roof is large. In a hamlet or village like Walton on the Hill, a postcode doesn’t always lead to the right gate, so a few directions are welcome. The visit itself is the same as anywhere else.
- You tell us where the water appears, when, and what the weather was doing.
- We examine the damp area and the rooms near it.
- From the loft space, we trace the water’s route where there is safe access.
- We inspect the likely entry points outside, from ground level, windows and the roof where safe.
- You receive a report with the likely source, photos and recommendations.
Getting ready for the survey
- Leave a clear route to the loft
- If you are buying, check with the agent that we can get in
- Make sure pets are kept safely away

Common questions in Walton on the Hill
Do you cover Walton on the Hill?
Yes. Our area covers London and South East England, and Walton on the Hill is part of that. Just phone 07833 053749 or use the contact form and let us know about the property.
Do you cover smaller places like Walton on the Hill?
We do. A small place gets exactly the same survey as a big one.
Can you survey at the weekend?
Visits run seven days a week in the daytime, which suits people who work during the week. Just say which days work for you.
Do you use thermal imaging to find leaks?
We use thermal imaging where it helps, and it’s included in our Premium Survey. It shows temperature differences, not water itself, so we confirm its findings with moisture readings.
How long have you been surveying roofs?
More than 5,000 surveys over 20+ years, across London and South East England.
What insurance do you have?
Our surveys are covered by professional indemnity and public liability insurance. Ask if you need details for a managing agent or building owner.
Can you tell me if my roof has asbestos?
No. We don’t carry out asbestos surveys or testing. We flag materials that could contain asbestos, like cement sheets or soffits on pre-2000 buildings, and recommend a specialist asbestos surveyor checks them before they’re disturbed.
Before and after the survey
These tips come from what we see on roofs every week:
- Tell us about any past repairs to the roof
- Take dated photos of the leak
- Keep water away from lights and sockets
- Check whether pipes or tanks run near the stain
If there are several possible sources, we list them in order of likelihood. We say which items need prompt attention.
Plan a roof survey every few years. They’re where most leaks start, and wear is easier to deal with before water gets in.
What we’re asked to look at in Walton on the Hill
When a slate slips or a tile cracks, the underlay takes the water. Ageing felt underlay eventually tears and lets water through, while some very old roofs have nothing under the coverings. Corroded nails, known as ‘nail fatigue’, are a frequent cause on slate roofs.
Here are some of the things we see frequently:
- Leaks below a flat extension roof
- Water coming in around a roof light or dormer
- Drips from nail tips in a cold loft
- A leak that comes and goes with the weather
For site and facilities teams at buildings such as Walton-on-the-Hill Primary School, a leak through a large roof is often found some distance from where the water shows inside.
